Tidelash (Mareflagellum berinu)

Alias: None
Origin: Berinu (tidal zones)

The Tidelash is a whip-like algae anchored in Berinu’s tidal zones. It moves violently with the pull of the tide, lashing outward to entangle small marine fauna, which decompose or feed larger aquatic life. Its presence helps sustain coastal food chains while adding to the hazards of Berinu’s shifting shores.

Terrain

Tidal zones, anchored in brackish waters. Absent in inland or arid biomes.

Lifespan

Lives 5–10 years. Matures at 1–2 years. Produces spores in tidal seasons.

Height & Spread

Reaches 2–4 meters in length, with a lateral spread of 0.5–1 meter. Juveniles range from 0.5–1 meter.

Uses

• Ecological Role: Entangles and breaks down small marine fauna, feeding into tidal food webs.
• Cultural Significance: Used by Berinese as a fishing aid, both directly and in net-making; symbolizes the fury and unpredictability of the tides.
• Guidance: Safely harvested during low tide. Strands may be woven into nets or traps.

Notes

Documented in the Era of Absolute Expansion (~3,000 years before modern Geba), Tidelashes remain a functional and symbolic component of Berinu’s tidal ecosystems. Extant and useful.
